Post-traumatic arterial priapism: Colour Doppler examination and superselective arterial embolization

Purpose: To evaluate selective embolization for management of post-traumati c priapism and colour Doppler sonography for the diagnosis of the causative lesion and for planning embolization. Materials and Methods: Six male patients with post-traumatic priapism under went selective angiography and embolization. Colour Doppler sonography with grey-scale was performed in all six patients before angiography. Results: Selective angiography showed intracavernosal arteriovenous fistula s in all patients and pseudoaneurysm of the cavernosal artery (or common pe nile artery) in three patients. After successful embolization, detumescence was achieved in all patients. Colour Doppler sonography enabled localizati on and characterization of the lesion causing priapism in four patients. Gr ey-scale ultrasonography showed the dilated cavernosal sinuses in all patie nts. Conclusion: Angiography with selective embolization is safe and effective m ethod to correct post-traumatic priapism. Colour Doppler sonography with gr ey scale is a useful preangiographic study, as it allows for characterizati on and localization of the causative lesion except lesions at the proximal cavernosal or distal penile artery near the symphysis pubis.
